Description:
This phase II trial studies the side effects and how well cladribine and rituximab work in
treating patients with hairy cell leukemia. Drugs used in chemotherapy, such as cladribine,
work in different ways to stop the growth of cancer cells either by killing the cells, by
stopping them from dividing, or by stopping them from spreading. Immunotherapy with
monoclonal antibodies, such as rituximab, may help the body's immune system attack the
cancer, and may interfere with the ability of tumor cells to grow and spread. Giving
cladribine together with rituximab may kill more cancer cells.

Purpose
This phase II trial studies the side effects and how well cladribine and rituximab work in
treating patients with hairy cell leukemia. Drugs used in chemotherapy, such as cladribine,
work in different ways to stop the growth of cancer cells either by killing the cells, by
stopping them from dividing, or by stopping them from spreading. Immunotherapy with

cladribine together with rituximab may kill more cancer cells.
Detailed Description
PRIMARY OBJECTIVES:
I. To demonstrate the efficacy in achieving complete response of combination of cladribine
administered intravenously over 2 hours for 5 days followed by rituximab weekly for 8 weeks
in patients with untreated or previously treated hairy cell leukemia.
II. To examine the efficacy of rituximab to eradicate minimal residual disease (MRD) after
cladribine therapy (as assessed by immunophenotyping of bone marrow and peripheral blood).
III. To examine the effect of addition of rituximab to cladribine on the long term
disease-free (DFS) and overall survival (OS) (as compared with historical controls).
IV. To evaluate potential predictors of outcome including molecular and flow evaluations of
MRD, as well as other potential molecular predictors such as v-raf murine sarcoma viral
oncogene homolog B1 (BRAF).
OUTLINE:
Patients receive cladribine intravenously (IV) over 2 hours once daily (QD) on days 1-5 and
rituximab IV once weekly for 8 weeks beginning on day 28 in the absence of disease
progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year.

Primary Outcome Measures
Measure: | Efficacy of rituximab on achievement of complete response after therapy with cladribine |
Time Frame: | At 12 weeks |
Safety Issue: | |
Description: | Defined as the absence of hairy cells in the bone marrow or the presence of less than 1 percent atypical cells and the disappearance of all evidence of hairy cell leukemia on physical examination. Monitored using the method of Thall, Simon, Estey as extended by Thall and Sung. |
